[Gate-users] Error in the phantom and detector tracking modes

[Pietrzyk, Uwe]

Hi Arda,

I briefly checked the example you have mentioned in your eMail,
namely: example_TrackerDetector with GateV7.1
In fact the rootfile in generated, but from GATE there are two problems
reported:

 <!> *** WARNING *** <!>  Unknown process: MultipleScattering
***** COMMAND NOT FOUND </gate/physics/processes/MultipleScattering/setGeometricalStepLimiterType e- distanceToBoundary> *****
and also the line:
GateToRoot::RecordEndOfAcquisition(): Failed to access to 'total_nb_primaries' histogram to fill it !

I can imagine that this entry is simply not generated within the TrackerDetector example,
but maybe more knowledgeable gate-users can answer this specific finding.
Can you use the data without having total_nb_primaries available?

Kind regards,

Uwe Pietrzyk
